To all/whom t may concern.-

Be it known that I, GEORGE P. Kir'rnn, a subject of the Emperor of Germany, (rst naturalization papers obtained,) and a resident of Union Hill, Weehawken post-office, in the county of Hudson and State of New Jersey, have invented a new and Improved Hydrocarbon-Burner, of which the following is a full, clear, and exact description.

This invention relates to a kerosene or other hydrocarbon burner of such type that the liquid fuel supplied thereto is vaporized in transit to the jet orice so that from the orifice a jet ofhigh velocity vapor is discharged and entrains air that mixes therewith, whereby a large, hot blue flame is produced.

The invention has for its general objects to improve the construction and operation of devices of this character so as to be reliable and efficient in use, comparatively simple and inexpensive to manufacture, and so designed as to enable the jet orice to be easily and quickly cleaned.

A more specific object of the invention is the provisionV of a burner having a novel arrangement of vaporizating coils, vflame de- Hector and starting burner.

An additional object is to provide a normally closed blow-out valve connected with the vaporizing conduit, which blow-out is adapted to be opened before the burner is shut down, so that a high velocity flow of vapor will be produced, which will carry out carbon deposits and foreign matter.

A further object of lthe invention is to so constructV the nozzle of the burner that the inlet end thereof is of such shape that Vthe lodging of foreign material thereon is reduced to a minimum, and furthermore, the nozzle is so relatedto the vapor supply pipe that by opening the pipe at a point beyond the nozzle the fuel vapor will shoot past the nozzle ata high velocity and free it from clogging matter.

Still another object of the invention is to provide a vaporizing starting coil in which the convolutions are in close contact and means are provided in connection with the coil whereby the said coil constitutes a combustion chamber for the fuel during the normal operation of the burner.

The invention also contemplates a new method of operating burners of the type referred to by thoroughly cleaning out the' vaporizer prior to the shutting down of the burner to cause a flow through the vaporizer at a much higher velocity than normal, this being effected by the opening of a blow-olf vent or relief which is of such size as compared to the aperture of the burner that the increased rate of flow carries out all deposits from the vaporizing conduit.

With such objects in view, `and others which Will appear as the description proceeds, the invention comprises various novel features'of construction and arrangement of parts which will besetforth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,

Figure l is a perspective view of the burner;

Fig. 2 is a vertical sectional view;

Fig. 3 is a longitudinal section of the nozzle pipe;

Fig. 4 is a detail view of the means for supporting the vaporizing coil on the de fiector plate; and

Fig. 5 isa detail view of the blow-off valve.

Referring to the drawing, 1 designates the burner nozzle, 2 the nozzle pipe, 3 the starting coil connected with the nozzle pipe, 4 the main vaporizing coil, 5 the deflector, 6 the deflector supports, 7 the base plate, 8 the starting pan or burner, 9 the liquid fuel supply valve, 10 the nozzle pipe extension, and ll the blow-out valve in the extension.

The nozzle pipe is doubled back over the pan 8, which latter contains asbestos or Vequivalent material that is adapted to be saturated with a suitable hydrocarbon so that when the same is ignited the flame will envelop the nozzle pipe 2, the nozzle and starting coil 3, which latter is located directly above the nozzle, with the axis of the coil and nozzle lsubstantially coinciding. The main vaporizing coil 4 is disposed in a horizontal plane and in `contact with the periphery-of the deiector 5, and theend 12 (of the coil 4 is connected by a drop 13Y with the upper end of the starting coil 3. The opposite end 14 of the main vaporizing coil is connected with the fuel valve 9, which in turn is connected with a suitable source of supply, not shown. The coil is connected with the deflector by means of clips l5, which straddle the coil and are bolted to the marginal portion of the deliector. The

under side of the deector is conical, with its vertex directly over the nozzle, so that the main flame will bedeflected in all directions outwardly to and against the main vaporizing coil, so as to eectively vaporize the fuel during the normal operation of the burner.

The starting coil. 3 is utilized to form a combustion chamber for the fuel vapor and air during normal operation. The convolutions of the coil 3 are in close contact, and welded or otherwise fastened to the bottom of the coil is a disk 3a, which is provided with an opening 3b centrally above the burner nozzle 1, and within the upper end of the coil is disposed an open-ended cylinder 3c welded or otherwise suitably secured to the coil. In this manner the amount of air entrained with the jet of fuel is restricted and combustion takes place within the chamber thus formed .by the coil 3, disk 3a and cylinder 3, and out of the top of this chamber the flame rises and is deflected by the `deflector 5 outwardly to produce a better 'heating effect.

The nozzle 1 comprises a plug which has a central jet orifice A16, and the lower inner end of the plug is pointed so thata comparatively sharp edge is provided at 17, which minimizes the possibility of particles lodging at. the entrance of the orifice 16. The lpoint ofthe plug lies within the bore of the nozzle pipe 2 and its eXtension, so that when the blow-out valve 11 is open, the vapor fuel under high pressure causes a high velocity flow past the nozzle plug, so as to clean off the mouth or entrance end of the plug. The valve 11 is of such size as compared with the burner nozzle and the vaporizing conduit that when the valve 11 is fully opened the rate of iow is considerably 'higher than normal, due to the difference vin pressure between the atmosphere and the normal vapor pressure, and this high velocity flow through the vaporizing conduit causes an effective cleaning out'of carbon deposits` and foreign mattei' from the vaporizing conduit and from the entrance of the bore ofthe burner nozzle. It is preferable to open the blow-off valve before the valve 9 is closed, so that the full head of the fuel supply will be maintained during the blowoff operation, and after the vaporizing conduit is thus `cleaned out the valve 9 is closed toshut off the flow of fuel.

' Fronithe foregoing description taken in connection with the accompanying,drawing,

the advantages of the construction and method of operation will be readily understood by .those skilled in the art to which the invention appertains, and while I have" described the principle of operation, together with the device which I now consider to be the `best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A burner comprisinga jet nozzle, a starting vaporizing coil connected with .the nozzle and disposed above the same in concentric relation thereto, means coperating .with the coil to form a combustion chamber hav'- ing a restricted opening at its bottom directly over the nozzle and separated therefrom for providing a free space for atmospheric air to be entrained with fuel vapor from the nozzle, a deflector disposed above the combustion chamber and separated therefrom by an open space through which the flame passes to the bottom of the deflector, and a main vaporizing coil associated with the deflector and connected with the starting coil.

2. A burner comprising a jet nozzle, a vaporizing starting coil disposed above the nozzle in concentric relation thereto and connected with the nozzle to supply vapor thereto, a main vaporizing coil disposed above the irst-mentionedcoil and connected therewith, a deiiector lying within the main vaporizing coil for deiiecting the flame outwardly against such coil, a starting pan under the nozzle, a base plate for the said pan, and supporting means between the base plate and the deiiector.

3. A burner comprising a jet nozzle, a vaporizing starting conduit formed of a coil having a plurality of convolutions disposed concentrically above the nozzle, a plate on the bottom of the coil and having an aperture directly above the nozzle, and means .in the upper part of the coil to cooperate therewith and the plate to form a combustion chamber, a deflector disposed over the combustion chamber, and a main vaporizing coil arranged in cooperative relation with the deflector and connected with the first-mentioned coil.
